Engineering Standards
10. Sidewalks Adjacent to Screening Walls – In areas where a screening wall is provided along a
thoroughfare, the outside edge of the sidewalk shall either remain a minimum of two feet (2’)
from the wall or the sidewalk shall be paved up to the wall.
11. Access Ramps – Barrier-free ADA access ramps shall be provided at all street intersection
corners, at all crosswalks, and across any non-residential or multi-family driveway.
12. Sidewalks on Bridges
a. All street bridges shall have a sidewalk constructed on each side of the bridge. The
sidewalk shall have a minimum width of six feet (6’) with a parapet wall that is separated

the center lane may be reduced to eleven feet (11’) and the shoulders may be reduced to
twelve inches (12”).
13. Sidewalks Under Bridges – When new bridges are built as a part of the construction of a
roadway or the reconstruction of a roadway and a pedestrian crossing is needed beneath the
bridge, a sidewalk shall be built as a part of the embankment design underneath the structure
for future hike and bike trails. The Hike and Bike Master Plan will designate whether a
sidewalk is built on one or both sides of the waterway and whether the sidewalk shall be ten
feet (10’) or twelve feet (12’) wide.
14. Sidewalks on Culverts – All culvert crossings shall have a sidewalk, a minimum of six feet
